Halifax in the spring of 1901, and is now in the collection 

 of Mr. Arthur Crabtree of that town, who obtained it from 

 a friend who saw the specimen in the flesh. It is very sur- 

 prising that this species is not somewhat more frequent in its 

 visits to our shores, when on passage to and from its 

 Scandinavian summer haunts, and yet I believe this to be 

 the first really authentic record of its occurrence in the 

 British Isles." 



Mr. W. Buskin Butterfield exhibited a specimen of the 

 Black-headed Wagtail, Motacillafeldeggi of Michahelles, which 

 had been shot near Willingdon, Sussex, on May 13th last, 

 and examined by himself in the flesh and in fresh condition. 

 The specimen had been compared with the series of M. fel- 

 deggi in the British Museum, and there could be no doubt 

 that it was rightly identified. It was a male in fine plumage. 

 The species was not known to have previously occurred in 

 the British Islands. 



Mr. Butterfield also exhibited two males of the Grey- 

 headed Wagtail, Motacilla borealis, Sundev., procured 

 on the same day and near the same place. One of these 

 specimens had been handled in the flesh, and the other 

 (a somewhat damaged bird) shortly after it had been 

 skinned. They presented slight differences, both in 

 coloration and in the length of the bill and claws, but 

 Dr. Bowdler Sharpe and Mr. Butterfield had found no 

 difficulty in matching them with examples of M. borealis in 

 the British Museum series. 



Mr. W. B. Tegetmeier exhibited some eggs of the 

 Common Duck (Anas boscas) to show how the colour of 

 the eggs could be varied by selection, also some spotted eggs 

 of Pheasants, and a white egg of the Red Grouse 

 (Lagopus scoticus). 



An interesting discussion ensued, in which Herr Nehrkorn, 

 Mr. Hartert, and others took part.
